4 Claims. (01.128-141) (Granted under the act ofMal'ch a, 1883; as

amended April 30, 1928; 370 O. G. 757) The present invention relatesgenerally to im-. provements in face masks and more particularly tofac'eprotecting masks for aviators. The present invention is a divisionof my copending application Serial No. 614,985, filed June 2, 1932,wherein I have disclosed a novel face protecting and protect the facefrom the elements while flying at high altitudes. I

' An object of the present invention is to provide in a mask of thischaracter means for supplying gas to the-wearer which is so constructedand arranged that the gases upon entering the mask are deflectedlaterally and distributed more generally throughout the entire mask. Inso doing direct contact of the entering gases with the face of thewearer is substantially prevented, providing for greatercomfort and.ease in breathing to the wearer.

efiected adjacent the discharge ends thereof and a more rapid exhaustingof the exhaled gases from the interior of the mask will therefore beefiected.

fleretofore in face masks of this general character considerabledifficulty has-been experienced in preventing the fogging of the gogglesworn: by the aviator by reason of the fact that the exhaled or othergases in exhausting through the eye openings of the face mask would becon-.

densed on striking the relatively cold surfaces of g the lenses of thegoggles and thus impair to a great extent the visibility aflorded thewearer.

A further object of the present invention,

therefore, isto provide in a mask of this character an arrangementwhereby the exhaled gases are prevented from reaching and exhausting"through the eye openings, which is accomplished by confining the exhaledgases in the area generally surrounding the discharge outlets of themask.

The present invention also has for an object the providing of a facemask which shall be of warm and durablematerial and which shallcontribute to the maximum comfort of the To this end the helmet formedofpliable leather with an inner lining of warm soft wearer.

-more partlcularlyto the drawings,-

wherein corresponding parts are indicated by like numerals'throughoutthe various views therej of, the mask in the preferredembodiment of myinvention herein illustrated comprises generally a facebody portion ll,a nose portion II, throat portion l2 and chin portion l3, the-edges ofthe respective portions being adapted to be sewed together by means ofturrier stitches with the corresponding edges of each portion. matchedtogether in the manner designated in Figs. '7 to 10 inclusiv'ely bymeans of the referenceletters A to H, thus forming a unitary structure.The face body portion- Ill isformed with spaceddarts l4 and ii at itsupperedgegas shown in Fig. 7, which are adapted to be stitched togetherand thereafter reinforced by" suitable reinforcing 5 strips [6, whichmay be sewed to the face portion I0, as shown in Fig.1. In a similarmanner the adjacent edges of the face portion ll 1 and chin portion l3and throat portion.- llnre I providedwith reinforcing strips l1 and It,as

shown in Figs-l and 2." Goggle openings 2'! are also formed inthe facebody portion l0. The

face mask is'laminated, is, it is'formed' of an outer layer is of softpliable leather and'aninner-lining 20 of warni soft material such aschamois. As will be noted by referring,to Fig. 2, the'nose portion.ll-is provided with apertures 22' and 23; respectively, within which areadaptedtobe re-I ceived the inlet tube 24 and exhaust tube 25 7respectively. The exhaust tube 25 is of'suflcient length to extendthrough an opening zs' i-ovided in the lower portion 21 of the face bodyportion.

A. cup-shaped disk 28 of resilient material, such -asrubberorthelike,ismmmtedattheinner end of said exhaust tube, whichis'adapted to conform to and closely contact with the lips of thewearer. I

The inlet tube 24 is closed at its inner end, as shown at 29, and isprovided with a laterally extending opening 30 for discharging oxygeninto the nose portion of the mask. It will be noted by referring to Fig.2 that the lower portion to retain the inlet tube properly positioned.

As will be noted by referring to Fig. 2, a padded roll of chamois 32 isdisposed on the inside of the mask adapted for making intimate contactwith that portion of the wearer's face generally surrounding the noseand mouth so that the entering gases are confined in the areasdesignated by letters A and B. In so doing the exhaled or entering gasesare prevented from reaching and exhausting through the eye openings 2|and fogging of the goggles will therefore be substantially prevented.

In order to fasten the mask in position and maintain the same in closecontact with the face, the. sides of the face body portion are providedwith a plurality of bands 33 of elastic material having the usualadjusting devices 34 for lengthening or shortening the bands. Thesebands also serve the purpose of maintaining the padded roll 32 inintimatecontact with the face of the wearer to prevent leakage of airfrom areas A and B into the areas generally surrounding the eyeopenings. The portion 35 intermediate of the eye openings 2| is slit andis provided with a tab 36 having a female glove button fastener 31secured at its free end adapted to cooperate withthe male fastener 38fastened on the upper face body portion. This arrangement permits thewearer to readily put on or remove his goggles without requiring removalof the face mask in so doing.

Figs. 3 to 5 inclusive illustrate a modification of the inventionillustrated in Figs. 1 and 2. In this instance the eye openings 2| areprovided with a padded section generally indicated by the numeral 39,which completely surrounds the eye opening, said section being soarranged as to make intimate contact with the face of the wearer aboutthe eyes, as is indicated in Fig. 5. In so doing the exhaled or enteringgases are prevented from reaching and exhausting through the eyeopenings to fog the goggles. The air inlet tube 24' in this modificationis provided at its inner end with a plurality of flexible rubber. disksIll and 4| cemented together at their peripheral edges to form a chamber42 'for receiving gases. The disk It, as will be noted by referring-toFig. 5, is provided with a plurality of openings 43, through which theentering gases are discharged laterally into the face mask.

In this modification the exhaust tubes 25' for exhausting the exhaledair from the interior of the mask are laterally disposed on the facebody portion ll of the mask. As will be noted by referring to Fig. 4,.openings 14 are provided on the face portion of the mask adjacent thenose portion ll within which the inner ends of the exhaust tubes 25' arereceived, the outer portion of the exhaust tube beingsecured to the facebody portion by means of retaining strips 45 of durable material such asleather. The outer ends of the exhaust tube 25' are extendedsubstantially to the peripheral edges of the face body portion as shownin Figs. 3 and 4. By means of this arrangement air currents flowing pastthe companying drawings and referred to in the 2 above description asthe preferred embodiment, is the most eiilcient and practical; yetrealizing that the conditions concurrent with the adoption of my maskwill necessarily vary, I desire to emphasize the fact that various minorchanges 2 in'details of construction, proportion and arrangement ofparts may be 'restorted to when a required without sacrificing'any ofthe advantages of my invention, as defined in the appended claims. WhatI claim as new and'desire to se 3 cure by Letters Patent is:
